Warm-up method for machine system

A warm-up method for a machine system including a machine component, a machine sensor configured to sense temperature of the machine component, and a processing unit electrically connected to the machine component and the machine sensor, the machine component being a transmission machine component, the method comprising steps of:

• A) activating, by the processing unit, the machine component to execute a warm-up operation for warming up the machine component;
• B) determining, by the processing unit, whether the machine component is warmed up based on a target temperature corresponding to the machine component and a temperature of the machine component that is currently sensed by the machine sensor;
• and
• C) when it is determined that the machine component is warmed up, making, by the processing unit, the machine component not execute the warm-up operation.
